Fyrisån
Fyrisån (, "the Fyris river") is a river in the Swedish province of Uppland, which passes through the city of Uppsala and ends in Lake Mälaren. The "Sala" river in Uppland was changed in the 17th century in memory of the Fyrisvellir battle, mentioned in the Icelandic sagas, as it was the belief that the marshy plains called "Föret" was the site of the famous Battle of Fýrisvellir in the late 10th century. Boats can sail up the river from Lake Mälaren all the way to central Uppsala where two weirs make further progress impossible. In the summer of 2007, the construction of a fish ladder began to enable the asp, an endangered and potamodromous fish, to pass the weirs and reach its spawning Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposited into water by aquatic animals.

Fyrisvellir
Fyrisvellir, Fyris Wolds, or Fyrisvallarna, was the marshy plain (''vellir'') south of Gamla Uppsala where travellers had to leave the ships on the river Fyris (Fyrisån) and walk to the Temple at Uppsala and the hall of the Swedish king. Etymology The name is related to, or derived from, Old Norse ''Fyrva'' which meant "to ebb" and it referred to the partially inundated soggy plains that today are dry farmland and the modern town of Uppsala. In medieval times, a royal estate called ''Førisæng'', "Fyris meadow", was located near this field. The small lakes ''Övre Föret'', "the Upper Fyri", and ''Nedre Föret'', "the Lower Fyri", are remains of this marsh and retain a modern form of ''Fyri'' (the -''t'' suffix is the definite article, which lake names always take in Swedish). The field went alongside what was renamed the ''Fyris river'' (Fyrisån) in the 17th century to make the connection between the river and the Sagas more obvious. Thunberg, Carl L. (2012).

Weir
A weir or low-head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the water level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. There is no single definition as to what constitutes a weir. ''Weir'' can also refer to the skimmer found in most in-ground swimming pools, which controls the flow of water pulled into the filtering system. Etymology The word likely originated from Middle English ''were'', Old English ''wer'', a derivative of the root of the verb ''werian,'' meaning "to defend, dam". The German cognate is ''Wehr'', which means the same as English weir. Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more Navigability, navigable by boat. In ...

The Uppsala River Rafting Event
The Uppsala River Rafting Event is an event organized in Uppsala, Sweden on Fyris, the Fyris River at the end of April each year. Started in 1975 by the students Anders Ahnesjö and Carl-Johan Hansson, the event is organized by the Uppsala Union of Engineering and Science Students (UTN). The River Rafting The rafting takes place on 30 April every year, Walpurgis Night. Normally about 100 participants float the Haglund bridge in Uppsala to Islandsfallet in home-built polystyrene rafts. Tens of thousands of specatators watch the event. The prizes are awarded by the principal of the university, the Rector Magnificus. A few of the rafts represent different organizations but the vast majority of the participants are students at the Uppsala_University, University of Uppsala or other universities. The River Festival The River Festival, which takes place during the preceding week, allows participants to build their rafts in the raft-construction area. During the daytime, there are ...

Spawn (biology)
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and amphibious animals reproduce through spawning. These include the following groups: * Bony fishes * Crustaceans (such as crabs, shrimps, etc.) *Mollusks (such as oysters, octopus, squid) *Echinoderms (such as sea urchins, sea stars, sea cucumbers, etc.) * Amphibians (such as frogs, toads, salamanders, newts) * Aquatic insects (such as dragonflies, mayflies, mosquitoes) *Coral, which are living colonies of tiny, aquatic organisms—not plants, as they are sometimes perceived to be. Corals, while appearing sedentary or botanical by nature, actually spawn by releasing clouds of sperm and egg cells into the water column, where the two mix. As a general rule, aquatic or semiaquatic reptiles, birds, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Migration
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Their movements are associated with ocean currents and with the availability of food in different areas at different times of the year. The migratory ...

Asp (fish)
The asp (''Leuciscus aspius'') is a species of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, minnows and related fishes. This species is found in continental Europe and western Asia. Taxonomy The asp was first formally described as ''Cyprinus aspius'' by Carl Linnaeus in the 10th edition of ''Systema Naturae'' published in 1758, the type locality being given as the lakes of Sweden. It is now classified in the genus ''Leuciscus'' within the subfamily Leuciscinae of the family Leuciscidae. Etymology The asp is a member of the genus ''Leuciscus'', a name derived tautonymously from the type species' name, '' Cyprinus leuciscus''. ''Leuciscus'' is from the Greek ''leukískos'', a “white mullet” which is a diminutive of ''leukós'', meaning "white", an allusion to the silvery sides of the common dace. The specific name, ''aspius'' , is a latinisation of asp, a name derived from ''esping'' or ''esp'', which are Swedish common name ...

Fish Ladder
A fish ladder, also known as a fishway, fish pass, fish steps, or fish cannon, is a structure on or around artificial and natural barriers (such as dams, locks and waterfalls) to facilitate diadromous fishes' natural migration as well as movements of potamodromous species. Most fishways enable fish to pass around the barriers by swimming and leaping up a series of relatively low steps (hence the term ''ladder'') into the waters on the other side. The velocity of water falling over the steps has to be great enough to attract the fish to the ladder, but it cannot be so great that it washes fish back downstream or exhausts them to the point of inability to continue their journey upriver. History Written reports of rough fishways date to 17th-century France, where bundles of branches were used to make steps in steep channels to bypass obstructions. A 1714 construction of an old channel bypassing a dam, "originally cut for the passage of fish up and down the river", is mentio ...

Battle Of Fýrisvellir
The Battle of Fýrisvellir was fought in the 980s on the plain called Fýrisvellir, where modern Uppsala is situated, between King Eric the Victorious and an invading force. According to Norse sagas, this force was led by his nephew Styrbjörn the Strong. Eric won the battle, and became known as "the Victorious". It is mentioned by Saxo Grammaticus in ''Gesta Danorum'' and in a number of medieval Icelandic sources, including ''Eyrbyggja saga'', '' Knýtlinga saga'', and '' Hervarar saga''.
